Start with the right potatoes—russets are ideal for a fluffy texture.
Boil potatoes until tender but not overcooked to avoid sogginess.
Use warm milk and melted butter to ensure smooth mixing.
Avoid over-mixing to prevent gluey texture; use a masher or ricer.
Season well with salt and pepper for balanced flavor.
For extra creaminess, add sour cream or cream cheese.
Serve immediately for the best texture; mashed potatoes firm up when cold.
